All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
Meteoroids generally do not pose much of a risk as they are generally small enough to burn up in the atmosphere, and do not reach the surface. Asteroids and comets are larger and can cause potentially catastrophic damage if they strike Earth.
The junk consists of the remains of the satellites that have been launched from Earth. They have outlived their usefulness and have been abandoned. Eventually their orbit decays and they fall back to Earth. Most will totally burn up due to friction in the atmosphere. Little of it will reach the surface. But it does pose a hazard to the launch of new satellites and spacecraft.

space satellites are in space and earth satellites are in earth.
Mars has two natural satellites. Earth has one.
Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.Communication satellites orbit around the Earth.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
Why would you classify the moon and earth as satellites?
No. The earth has one natural satellite ... the moon ... and any number of other satellites whose primary purpose is not scientific (e.g. communication satellites).
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
